I've got a similar motherboard to the original poster (a Tyan S1836DLUAN/GX
instead of S1832DL), and ran across essentially the same problem -- the
interrupts for the ahc controller weren't working -- with the new interrupt
code. With the new kernel, booting with ACPI disabled worked okay, but
booting with ACPI enabled caused the SCSI device probe to hang up. This is
true even for a kernel compiled from current source today. Below I list
the dmesg output for a boot with today's kernel with ACPI disabled. Alas,
I don't have a similar file for the ACPI-enabled case (since the OS doesn't
ever get up to a point where it can write to its disks, and don't have a
machine available for ready serial console-ing), but I can tell you that
where the non-ACPI boot said
pcib0: slot 7 INTD routed to irq 19
pcib0: slot 17 INTA routed to irq 19
pcib0: slot 18 INTA routed to irq 16
pcib0: slot 18 INTB routed to irq 16
the booted-with-ACPI kernel said those interrupts were routed to IRQs 11 and
10, respectively, and the later ahc? probes said that ahc[01] were on irq 10
as well.
I'd attach the dump of the ACPI tables as well, but, um,
ichotolot# acpidump -t
acpidump: sysctl machdep.acpi_root does not point to RSDP
ichotolot# sysctl -a | grep acpi_root
machdep.acpi_root: 0
ichotolot#
So you can't dump the ACPI tables for debugging purposes if you didn't
boot with ACPI? I don't recall this being the case before...
